C# linq no data selected

Question

In a C# 2008 linq statment that looks at a directory path below, I am having problem with the following code.
string[] excelFiles = Directory.GetFiles(strFullpath, "*.xlsx")
.Select(path => Path.GetFileName(path))
.ToArray();
If there are no records selected, the code is caught in a try catch-block.
How can I change the code listed above to check for records when no records are selected  for the string[] excelFiles array?
Also if possible, how can I change the statment above to allow me to check for no records and/or if the string[] excelFiles array is not even created?

Even if there are no records, the ToArray() method still produces an array object but it's empty i.e. its length is zero.
Consequently, you can check whether there are any records or not like this:
if (excelFiles.Length > 0) {    // there's at least one record } else {    // there are no records }
